復制API代碼到窗體代碼結構函數下方，引用命名空間，委托MouseDown的事件（李獻策lxc）

//窗體陰影API，放在結構函數上方，修改結構函數即可const int CS_DropSHADOW = 0x20000;const int GCL_STYLE = (-26);[DllImport("user32.dll", CharSet = CharSet.Auto)]public static extern int SetClassLong(IntPtr hwnd, int nIndex, int dwNewLong);[DllImport("user32.dll", CharSet = CharSet.Auto)]public static extern int GetClassLong(IntPtr hwnd, int nIndex);public Form1(){InitializeComponent();SetClassLong(this.Handle, GCL_STYLE, GetClassLong(this.Handle, GCL_STYLE) | CS_DropSHADOW);} 窗體陰影API

復制API代碼到結構函數上方，修改結構函數即可

API - 通用功能接口

做一個如下無邊框的窗體

一、無邊框窗體移動

復制API代碼到窗體代碼結構函數下方，引用命名空間，委托MouseDown的事件

public Form1(){InitializeComponent();}//窗體移動API[DllImport("user32.dll")]public static extern bool ReleaseCapture();[DllImport("user32.dll")]public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int IParam);public const int WM_SYSCOMMAND = 0x0112;public const int SC_MOVE = 0xF010;public const int HTCAPTION = 0x0002;[DllImport("user32")]private static extern int SendMessage(IntPtr hwnd, int wMsg, int wParam, IntPtr lParam);private const int WM_SETREDRAW = 0xB;private void Form1_MouseDown(object sender, MouseEventArgs e){if (this.WindowState == FormWindowState.Normal){ReleaseCapture();SendMessage(this.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0);}} 無窗體移動代碼 復制后

二、窗體陰影
